Cloud Biocep


Published on

With Biocep-R, We propose to build on top the mainstream Statistical and Scientific Computing Environments (R,cilab, Matlab, SAS..) a federative and user-centric OSS platform for High Performance Computing, data analysis and collaboration. Biocep-R computational engines can be running locally or remotely (on Servers/Clusters/Grids/Clouds) and can be accessed from the Researcher's laptop. The Researcher can use an extensible cross-platform workbench to pilot the engines and can also control them programmatically.

The workbench includes highly programmable server-side spreadsheets fully integrated with the SCEs functions and data and that can be mirrored to Excel's spreadsheets.
Multiple Researchers can connect simultaneously to the same the remote computational engine and use it collaboratively via a set of broadcasted views .

The Researcher can easily create or connect to multiple engines running on one or multiple heterogeneous infrastructures and use them for parallel computing. The plug-ins architecture offers a highly innovative way to produce and distribute SCE-based User Interfaces for Academia (Science gateways) and Industry (Financial Dashboards, What-if-analysis user interfaces, analytical applications...). Biocep-R on local virtual appliances opens new perspectives for reproducible computational research.

Virtual Machines with R,Scilab and Biocep are publically available on Amazon's Elastic Cloud and can be run on demand to perform statistical/numerical computing using "unlimited" computational and storage resources. The Presentation will give an overview of this new platform and the main usage scenarios will be demonstarted.

  3. 3. Definitions ♦ What is the Cloud ? Cloud computing is a paradigm of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them. Wikipedia Cloud Computing represents a new way to deploy computing technology to give users the ability to access, work on, share and store information using the internet. The cloud itself is a network of data centers- each composed of many thousands of computers working together- that can perform the functions of software on a personal or busisness computer by providing users access to powerful applications, platforms and services delivered over the internet. Jeffrey F. rayport & Andrew Heyward (Marketplace LLC) ♦ What is R ? Open-source (GPL) software environment for statistical computing and graphics Lingua franca of data analysis. Repositories of contributed R packages related to a variety of problem domains in life sciences, social sciences, finance, econometrics, chemo metrics, etc. are growing at an exponential rate. ♦ What is Scilab ? Open-source (CeCILL) software package for numerical computations. Clone of Matlab. Widely used for engineering and scientific applications. ♦ What is an SCE ? Scientific Computing Environment : enables users to solve a wide variety of problems through flexible user interfaces that can model in a natural way the mathematical aspects of many different problem domains. Examples : Matlab, Mathematica, Scilab, R..

  11. 11. Shell’s Biocep-R-based statistical modelling cloud computing pilot Extracts from Shell’s cloud computing big rules document : < The Global Solutions statistics group actively uses the open source “R” statistical modeling tool. An inexpensive platform upon which to run the statistical models was required with the ability to scale up and down depending on calculating demand. In order to achieve this, the pilot created an analytical application using a pool of stateless and, more importently, statefull “R” engines across multiple servers in Amazon using Biocep for integration and virtualisation of the “R” engine. Using Amazon enabled them to have ♦ On-demand access to high-powered computing facilities. Numerically intensive statistical applications can be handled by the cloud rather than slowing down the users own PC. Could be of great benefit in the Bio-Fuels research area, which will require very computationally intensive statistical techniques.
  12. 12. ♦ Disaster Recovery: By using virtual machine images on the cloud we can always restore to the initial state. If something goes drastically wrong with the cloud machine image we can simply scrap it and launch another instance. Safer to implement web apps on a virtual machine using AWS rather than in-house server. ♦ The Cloud can be used as a real-time collaborative workspace. Co-workers can work together and share statistical methodologies in a new and novel environment. ♦ The onset of Cloud Computing has greatly increased the availability of software for delivering web-based statistical applications. The benefits of which include: o No special configuration or changes are needed on users PCs. o No need for scripting of applications. o Compatible with all operating systems. o Updates can be made quickly and easily in a centralized manner. o Everybody has a browser. Familiar interface encourages use. o Statistical web-based applications can either be hosted on the cloud or an in- house Shell server: which may be more appropriate for most confidential data. > Contacts within Shell : Edwin Vansteenis, Shell Global Functions, Senior IT Architect, Wayne W.
